Carbon capture and storage (CCS) is an area of technology that has received national and international attention. CCS is seen by some as a way to reduce carbon dioxide (CO2) emissions into the atmosphere and thereby decrease the threat…
To many, the concept of a "smart plant" involves integrating critical process subsystems and instrumentation with the goal of streamlining operations, increasing production and, simply put, making more money. But looking at the bigger picture, the true goal of having…
Accurate temperature measurement is not difficult. It does, however, require you to think about accuracy from specification and selection, all the way up to installation and operation of your temperature-measurement sensor. There are opportunities to improve accuracy during each of…
FIGURE 1. In a typical system for wastewater treatment, the liquid feed is introduced at the top of the column and steam is introduced at the bottom In recent years, steam strippers have become integral parts of industrial plant…
Most common acids can be stored in horizontal or vertical ASME-type tanks, as shown in the figures to the right, or vertical API-type tanks. Horizontal, carbon-steel ASME-type tanks of 10,000 — 40,000 gal capacity should have a plate thickness of…
Effective use of capital in the ownership and management of manufacturing assets is critical to the financial performance of companies in the chemical process industries (CPI). Many of these companies use benchmarking in compliance with applicable laws and antitrust…
A. Alexander and F. Muzzio, Rutgers University Proper blender selection can improve the mixing of bulk solids. Be sure to consider post-blending segregation problems Mixing and blending of bulk solids occurs frequently in many industrial processes. Though small-scale mixing and…
Demands in the chemical processing industry to reduce energy consumption and carbon footprint are higher than ever before. Correct sizing and selection of vacuum systems can contribute significantly to optimizing throughput and efficiency, thus reducing energy consumption, capital and running…
This fifth in a series of articles [1 – 4] on piping design discusses the practical issues of installation and cleaning. Pipe installation The installation of pipe follows its fabrication and is very frequently a part of it. The…
A good understanding of the reaction chemistry is needed for a safe process design It is a fact that safety-related incidents do occur in the chemical process industries (CPI). These incidents have, in part, led to increased attention to reactive-chemical…
